In operation, liquid to be filtered is delivered by a pump 41 to the filter 22, valves 50, 52 being opened and a valve 54 in the sludge outlet being closed. As the filters 40 became clogged, the pressure in the filter casing increases until a pressure switch 94 is actuated which causes the motor driving the pump 41 to be switched off, the valves 50, 52 to close and the sludge valve 54 to open. A valve 88 is also opened and compressed air admitted to the filter which quickly forces the sludge into the compartment 98. With a drop in pressure due to the sludge removal the pump 41 is again started valves 50, 52 opened and valves 54, 88 closed. Air is supplied to compartment 98 forcing the liquid through the filter 96 to compartment 100 from where it is returned to the supply tank 42, while the sludge is deposited on the filter 96. A delayed action control causes the air supply to be discontinued and the ram 136 to be actuated to lower the compartment 100. Movement of the compartment acts through switches 182, 188 to start a motor 178 which drives the endless belt and filter paper until the sludge is removed. The motor is then stopped and the compartment 100 raised ready for the next sludge disposal cycle.
